Today i noticed several gold spots that actually looked like gold flakes along the back of my Koi ? i was told about a fish disease called "Velvet?" but all references were directed at tropicals , anyway they are along the back , The koi was/is acting strange like flashing several times , for a few day was jumping a couple of times a day , sits in a corner a lot but is active especially when i approach pond or throw food in , i have observed him/her eating but none of the fish come to the surface to feed they wait for the waterfall current to drag food under , the koi is very active in the evening , as are the other fish ( gold fish) should i treat this fish and for what and with what should i treat the pond should i add salt to the water , or even pima/melafix should i add some stress coat ????? anyone viewing , leave a message nothing more irritating than seeing 100 viewers and 0 replies !
